register serializable data objects with decorator

[seb5g]

This PR is somewhat related to PyMoDAQ/PyMoDAQ#543

The issue happened mostly because deserialization of data objects unknown of the factory would fail. There is a registration mechanism present in the new method of the object. This would automatically register these (and all their inheriting objects) IF THEY ARE AT LEAST ONCE INSTANTIATED. On the machine/interpreter where the LECO director runs it can receive objects to deserialize while such objects have never been instanciated and there fore not registered. In this PR, I explicitely register known objects now to overcome this. It will be done also for specific objects on the pymodaq side
